SPECIFICATION formingpart of Letters Patent No. 704,906, dated July 1 5, 1902.

Application filed June 24, 1901.

To all whom it may concern.- 1

Be it known that 1, WILLIAM HARVY"1lIO-' WILLIAMS, a citizen of the United States, and a residentof atonga, in the countyof Elaine and Territory of Oklahoma, have invented a new and Improved ind-Stacker, .of which the following is a full, clear, and exact description. v

The purpose 'of the invention is to provide a wind-stacking attachment to threshing and similar machines, so constructed that the fan, which is a suction-fan, is located at the upper portion of the rear part of the body of the machine at a point above the conveyor-belt adapted to carry up straw and to so locate the fan relative to the conveyor that the straw will be stacked up by the fan, the straw passing through the casing in which the fan re volves to a stacking-tube, while the grain] which is heavier than the straw, will drop from the conveyer to a conductor and .be directed to the riddles, thus providing a convenient means for removing the straw and a means which will cause the least possible waste of grain.

The invention consists in the novel con-' struction and combination of the several parts, as will be hereinafterfully set forth, and pointed out in the claim. j

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the rear portion of a threshing-machine with the attachment applied, parts of the attachment and parts of the machine being in section. Fig. 2 is a horizontal section taken practically on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken substantially on the line 3 3 of Fig. 1. Fig. 4 is a horizontal sectiontak'en substantially on the line 4 4 of Fig. 1.- Fig.

5 is a vertical section taken substantiallyon by the casing 11, as is shown in Fig. 5.

Serial No. 65,845. (No model.)

ashield 10 is located, which curves up at the "rear of 'theconveyer.

This shield is adapted toreceive the grain and conduct the same to the riddles of the machine. The casing 11 stacking-tube maybe of'any suitable construction and is mounted to turn at its bottom portion,

Asuction-fan 15 is located in the casing 11,

and the blades of this fan, as shown in Figs.

1 and 2, are moreor less inclined, being at more or less of an acute angle to the hub of the fan. The lowercentral portions of the blades are cut away to a greater or less eX- tent over the opening 12, so as to permit the vstraw to be sucked up from the body of the machine by the fan and conduct it out through the outlet-opening 13 to the'stacking-tube 14. The fan is secured to a shaft 16, and this shaft extends upward from the central portion of the casing 11, as is shown in Fig. 5, and is journaled at its upperend in a suitable bearing 17, secured to a frame 18, carried by the casing; A bevel-pinion 19 is secured to theupper end of the shaft 16, and this bevelpinion meshes with a bevel-gear 20, the gear ':'being secured to the inner end of a driveshaft 21, mountedin bearings 22, secured .to a second frame 23, which is also supported The shaft 21 carries a pulley 24 at its outer end, which is'connected bya belt 25 with any nearby source of power.

At. the bottom portion of the stacking-tube 14 a bevel-gear 26 is secured. This stackingtubeis adapted to have motion alternately from right to left and from left to right, and the gearing usually employed to accomplish this end is that shown in the drawings, which gearing consists of a bevel-pinion 27, meshing vwith the gear 26, and this pinion 27 is secured to ashaft mounted in suitable hearings on the frame 23, as shown in Fig.'j4, and abevelpinion'28 is secured'at theinner end of this shaft. A second shaft 31 is journaled in bearings attached to the two frames 18 and 23, and this shaft 31, which is also a drive-shaft, has two pinions 29 and 30 loosely mounted thereon, both of which pinions engage with the inner pinion 28 of the short shaft connected with the stacking-tube.

A double clutch 32 is mounted to slide 'upon the drive-shaft 31 and turn therewith, the clutch being located between the pini'ons 29 and 30, as shown in Fig. 6, and the clutch is alternately brought to engagement with one or the other of the pinions 29 and 30 through the medium of a shifting-lever 33, operated in any suitable or approved manner. The shaft 31 is provided at its outer end preferably with a sprocket-wheel 34, connected by a chain belt 35 with any source of power.

When the fan 15 is located, as above described, at the upper portion of the body A of the machine, a door 36 may be located at the rear of the machine, enabling a person to readily reach the riddles and adjust the same.

The lever 33 is moved to operate the clutch (shown in Fig. 6) usually through the medium of arms 40, preferably adj ustably connected to the gear 26 on the stacking-tube 14. As these arms are brought alternately in engagement with the lever 33 said lever is carried first to one side and then to the other, causing the stacking-tube to swing from right to left and then from left toright, and vice versa.

In operation the fan 15 sucks up the straw and forces the straw into the stacking-tube, while the grain, which is carried up by the Having thus described my invention, I

claim as new and desire to secure by Letters Patent A wind-stacker for threshing-machines, comprising a conveyer for carrying mixed grain and straw, a fan for separating said grain from said straw, a vertical shaft for supporting said fan, a substantially cylindrical casing surrounding said fan,a revoluble member journaled upon said casing and provided with gear-wheels, a pair of gear-wheels mounted upon said casing and operatively connected with said revoluble member, said gear-wheels being disposed oppositely to each other and upon opposite sides of said shaft supporting said fan, a cylindrical stackingtube, an annular bevel-gear rigidly secured thereto and meshing with one of the gearwheels upon said revoluble member, a clutch, and a lever for actuating said clutch.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
